Clean hydrogen on a priority value chain platform can provide energy incentives and reduce environmental impact. In the current study, a Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis was successfully applied to the clean hydrogen value chain in various sectors to identify the strengths, weaknesses, opportunities, and threats of the Japanese clean hydrogen value chain as a case study. Japan was chosen as an example because we believe that it is the only pioneering country in this chain with a national strategy, investments and ongoing projects that make it unique in this way. The analysis includes an assessment of clean energy development, electricity supply chains, regional energy planning, and renewable energy development, including internal and external elements that may affect the development of the hydrogen economy in Japan. Japan’s ability to produce and use large amounts of clean hydrogen at a cost competitive with fossil fuels is critical to the country’s future success. Implementation of an effective carbon tax and carbon pricing is also necessary for cost parity. The need for global policy coordination and interdisciplinary cooperation will increase. The results obtained from this research will be a suitable model for other countries to be aware of the strengths, weaknesses, opportunities and threats in this field in order to make the right decisions based on their infrastructure, potentials, economy and socio-political states. to accept in that field.
Australia’s Transport Emissions: The Role Of Hydrogen In Reaching Zero Emissions
Since the ratification of the Paris Agreement in 2015, 195 signatory countries have committed to tackling climate change and setting global temperature limits through INDCs with medium- and long-term targets (2030) . To reach 1.5 °C by 2050, IRENA has allocated an emission contribution of 8.4 GtCO
The energy transition is a trend in which the world’s energy infrastructure will change from fossil fuel to zero carbon between 2050 and 2100. The need to control climate change by reducing CO2
Waste is its main purpose. Decarbonisation of the energy sector requires an urgent global effort. As the world’s energy transition begins, further steps are needed to reduce carbon emissions and mitigate the effects of climate change . The transition is a long-term investment opportunity that will fundamentally change the energy sector for the next 30 years and well beyond . An important issue is that in order to achieve the climate goals, investments are needed in the entire value chain, including all sectors of the global economy . To this end, accelerating the adoption of climate change mitigation policies, especially renewable energy carriers such as hydrogen, may offer a solution through the use of hydrogen as a source of energy storage. In general, there are three types of hydrogen: gray hydrogen, which comes from fossil fuels, and manufactured CO

What’s The Role Of Hydrogen In The Clean Energy Transition?
Taken during the process; and green hydrogen derived from renewable energy . Therefore, the importance of green hydrogen becomes clear when there is no superior alternative for decarbonization, especially for energy-intensive industries.
Hydrogen and hydrogens have special characteristics; for example, they are adaptable, sustainable and safe energy carriers that can be used as fuel for electricity generation or as raw materials in industry . Hydrogen can be produced using renewable energy with no emissions or low carbon emissions. It can be stored and transported in liquid or gaseous form with high energy density . It can be burned or used to create heat and power using fuel cells . Although hydrogen is now widely used in several fields, its potential to aid in the transition to sustainable energy has not been fully exploited . Ambitious, targeted and short-term measures are needed to further remove barriers and reduce costs . Green hydrogen is an environmentally friendly alternative that can be used for a number of reasons (energy storage, industrial processes and traffic, for example) without polluting emissions .
However, infrastructure and network upgrades are needed to make hydrogen as common and widely available as natural gas is today . In addition, the ability of hydrogen to flow from pipelines approximately three times faster than methane makes it a cost-effective alternative for large-scale hydrogen transport . For hydrogen to be available at the right time, it must first be produced and then stored and distributed in the value chain. The low density of hydrogen requires a large amount of storage at high pressure and temperature . Transport and storage infrastructures typically require high-capacity solutions, which can be considered a bottleneck .
Today, almost all hydrogen production in the world is gray hydrogen, including 48% from natural gas processing, 30% from petroleum byproducts, 18% from coal gasification, and the remaining 4% from water electrolysis . Depending on the stock of raw materials, 9-12 tons of CO are used in the process of processing fossil fuels
Iea At Cop26: The Role Of Hydrogen In The Transition To Net Zero
Per ton of hydrogen produced . By substituting hydrogen derived from zero-carbon energy sources for hydrogen derived from fossil fuels, the carbon footprint of energy-intensive industries can be significantly reduced . The applications of carbon-free hydrogen in energy systems, whether in transport, industry, construction or energy sectors, are diverse . Hydrogen can be used as a fuel to power vehicles and electrical appliances through fuel cells and ICEs. The high density of hydrogen in the liquid state allows it to provide propulsion power for spaceships. It can produce combined heat and power (CHP) on a small scale in residential fuel cells as a prime mover [18, 19].
Like natural gas, hydrogen can be compressed or liquefied for transport. For some countries, such as Japan as an island nation, this is the only option to purchase large quantities of this zero-emission energy carrier. Furthermore, excess renewable energy can be used to produce hydrogen for energy storage . This hydrogen can be mixed in limited quantities with natural gas in the grid or converted to hydrogen carriers such as methane, methanol or ammonia for storage . Hydrogen produced by electrolysis of water with renewable energy sources or from fossil fuels with a carbon storage unit becomes a fuel that stimulates economic development and contributes to the decarbonization of energy systems . The hydrogen value chain (see Figure 1) can serve as the basis for a clean energy system and is promising as a safe and sustainable energy carrier.
To better understand the economics of hydrogen, we need a full understanding of the value chain of clean hydrogen production. Hydrogen can be based on fossil fuels or completely renewable. Each country will decide on this based on its assets and experience. To the authors’ knowledge, this type of analysis has not been studied in the hydrogen value chain. In this study, a SWOT analysis was designed to analyze strategies for a successful energy transition to clean hydrogen. SWOT analysis is widely used in strategic planning [23, 24], because it provides an important basis for understanding the state of the object under investigation and developing plans to solve existing problems. Then the measures to encourage its development by using the strengths, reducing the weaknesses, taking advantage of the opportunities and avoiding the threats were proposed.
